Abstract :
Aims: To evaluate the sorption and solubility of three restorative materials in three different mouthwashes.
Methods and Material: A total of 45 samples of restorative materials were made in a stainless steel mould
of 15 -0.1 mm diameter and 2mm thickness as per ISO guidelines and three groups (n=15); Group I: Type
IX Glass ionomer cement (GIC ), Group II: Cention N and Group III: composite ,were assigned. After
measuring weight of the samples before immersion (m1) using digital analytical scale, 5 specimens from
each group were immersed in the mouthwashes and grouped as Subgroup 1: Listerine, Subgroup 2:Plax,
Subgroup 3: Periogard for seven days. Then the weight after immersion (m2) and the weight after final
drying (m3) were determined using the same digital analytical scale and values were estimated using the
Oysaed and Ruyter formula.
Statistical analysis used: The data were statistically analyzed using two way ANOVA followed by Tukey’s
post hoc test.
Results: The three mouthwashes had effect on sorption and solubility of tested materials. Type IX
GIC showed maximum sorption and solubility when compared to Cention N and composite. Among
mouthwashes, listerine showed significantly higher values when compared to Periogard and Plax.
Conclusions: Mouth washes having alcohol content with low pH may increase the sorption and solubility
of all the tested materials. Also the type and mean particle size of filler, the coupling agents, and the solvent
in which they are immersed affect these two properties.
